GPT and Duchenne muscular dystrophy: Levels of circulatory aspartate transaminase (AST) and alanine aminotransferase (ALT), which rise in DMD patients (McMillan et al, 2011), were significantly decreased in mdx mice treated with PMO‐M, whereas there was no significant change in levels of serum liver enzyme gamma‐glutamyl transferase (GGT) (Fujii et al, 2020; Fig 6A), creatinine (CREA) and blood urea nitrogen (BUN) (Fig 6B), markers for kidney function (Uchino et al, 2012), in mdx mice treated with PMO‐M compared to PMO alone and untreated mdx controls.
